“This is my first time at Warped Tour, and it has been awesome,” said Ashley Kearns, a fan from Austin. “It's not often you get to see this many bands all at once.”

The mosh pits and crowd-surfing didn't start too early. At the Memphis May Fire show early in the day, fans surrounded the stage and had crowd surfers as the band kicked off the tour's San Antonio stop.

“I came too see Mayday Parade, Memphis May Fire and The Used,” said Andrea Casas, who traveled from Edinburg, expressing what seemed to be the consensus.

With temperatures reaching the high 80s, staying cool wasn't really an option. Although clouds were hovering, the relief didn't last for long, and shaved ice, water and misting stations were popular. Shady areas under trees and tents were filled with fans standing, sitting and napping.

Klean Kanteen provided a free filtered-water refilling station to keep fans hydrated. Even a slip-and-slide was set up to help with the heat. Kids brought water-filled Camelbaks and traditional water bottles from home, and some wore swimsuits to help beat the heat.

“This is my third Warped Tour,” said Rebecca Lozano, a fan from Monterrey, Mexico, wearing a bikini. “After I got burned the first year, I learned my lesson” — wear a swimsuit and use sunscreen.

Activities to help pass the time included band signings and paraphernalia, a half-pipe for skating, and of course food.

“The crowd's been pretty awesome today,” said Haley Larranaga, a volunteer vendor for the band Hollywood Waste. “I did this last year and it was a lot of fun.”

The 41-day rock festival has been touring since 1995. This is the fourth year it's appeared at the AT&T Center, its first stop on the Texas leg. More than 16,000 tickets were sold for the event.
